'I'his invention relates to new and useful improvementsin a machineadapted to paint various colored and spaced bands on drinking tum` blersor similar articles. As a new decorative idea it is now popular toornament drinking glasses with a series of spaced painted bandsextending around the periphery of the glass. These bands may be equallyor unequally spaced and may be of similar or contrasting colors,according to taste.' To perform this work by hand is tedious anddifficult and necessitates a much higher price being charged for thefinished article.

The primary object of the invention herein described is to provide amachine which will neatly and eiectively perform this function and whichis practically automatic, so that a person vwith no particular skill canoperate it and so decorate many tumblers in a minimum of time.

Another object is to provide an adjustable mechanism whereby paintedbands may be placed around the periphery of a tumbler in predeterminedspaced relationship.

Still another object is to provide such a machine whereby such bands maybe so placed in predetermined color combinations.

A further object is to provide novel means for agitating the paintcontained in the reservoirs so as to maintain a constant smoothmixture'.

Another object is to provide novel yieldable paint applying discswhereby any slight differences in the surfaces of the tumbler or thediscsis compensated for.

Still a further object is to provide acushioned chuck for holdingtumblers to be so decorated and a stop member adjacent said chuckwhereby the relative position of the tumblers and the paint applyingdiscs is constant.

Another object is to provide means for manually rotating the tumblerafter the paint has bee'n applied so as to smooth out any gobs of paintlwhich may collect on the decorated area. Another object is to provide alock meansfor holding the tumbler o n the chuck.

Further objects and advantages will be apparent from the. drawings andthe description.

The banding machine comprises generally a chuck assembly A for receivingand rotating the tumblers to be decorated, a carriage member B on oneend of which is mounted the chuck assembly A'and which is pivotablevertically and movable horizontally, a plurality of paint reservoirs Cadapted to contain paint, enamel or other coloring matter, paintagitators D and a series of paint applying discs E, rotatably mountedona shaft assembly F between the chuck assembly A and the paintreservoirs C.

In detail the chuck assembly A comprises a shaft l rotatably mounted bymeans of ball bearing assembly 2 within the rectangular block 3 which isadjustably secured by means of stud and nut 3c to arm 4 extending fromone end of the carriage member B and which also carries handle 5. On'one end of shaft 1 adjacent block 3 is a knurled wheel 6 for manuallyrotating the shaft and adjacent the other side of block 3 on shaft l.i's mounted a drive wheel 7. Adjacent wheel 7 is mounted a stop disc 8adapted to contact with the rim of the tumbler 9 to limit longitudinalmovement and a centering disc 8a adapted to contact the inner edge ofthe rim to insure true rotation of the tumbler. The chuck propercomprises a tapered cylinder 10 mounted onthe shaft 1, its larger endtowards stop member 8, and movable longitudinally with relation thereto.A helical spring l1 is positioned about the shaft 1 and fits within aseat 12 formed within chuck 10 and isadapted to force chuck 10 away fromstop member 8. A bolt 13 is secured within theother end vof shaft 1,thel enlarged circular head 14 thereof forming a stop adapted to preventchuck 10 from being forced off the shaft 1 by spring 11.

A locking mechanismfor holding the tumbler 9 on chuck 10 is provided andcomprises a supporting ring arm 15 secured to the carriage member B andextending to a point adjacent the smaller endof chuck 10. Mounted onsaid arm so as to be vertically pivotable is a bracket 16 and on saidbracket is mounted a locking lever 17 adapted to be slightly pivoted ina horizontal plane. Lever 17 carries a handle 18 and a sphericallyheaded bearing member 19 adapted to contact the center of Bassum) thebottom outside surface of the tumbler 9. A coiled spring 20 positionedbetween the other end of said lever 17 and bracket 16 causes the bearingmember 19 to press against the tumbler. An adjustable screw and lock nutassembly 21 provides a stop means for limiting the downward pivotalmovement of bracket 16. Thus by means of handle 18 the lever 17 may bemoved horizontally a slight distance so as to bring bearing member 19out of contact with the bottom of tumbler 9 and then swing upwardlytogether with the bracket 16 so that tumbler 9 may be removed andanother one placed on chuck 10.

The carriage member B comprises a rectangular frame 22 on one end ofwhich are mounted the chuck assembly and locking mechanism ashereinabove described, and on the other end of which is slidably mounteda counterweight 23 and spacers 23a. Clamp screws 23h lock counterweight23 in proper position. A cylindrical track or rod 24 is mounted at rightangles to frame 22 and parallel to chuck assembly A by means of verticalbrackets 25 bolted on the base 26 of the machine. Frame 22 is mounted ontrack 24 so as to be vertically pivotable and horizontally movable fromone of its two alternative operative positions to the other by means ofthree flanged wheels 27 secured to frame 22 between its ends. The wheelsare in the same vertical plane but two of them ride on the top surfaceof rod 24 and the other is positioned below said rod and between theother two. Two similar bifurcated support members 28 are verticallymounted on base 26, one adjacent the chuck assembly carrying end ofcarriage member B in each of its operative positions and adapted toreceive arm 4 of frame 22 to prevent horizontal movement of frame 22when in operating position. Stop members 29 are positioned at each endof track 24 to limit the length of track over which frame 22 can behorizontally moved so that one of the support members 28 and arm 4 arealigned at each terminal point. Thus it is clear that by grasping handlethe entire chuck assembly may be lifted upwards (the frame 22 pivotingabout rod 24) and then moved horizontally between the two stop members29 on the track 214. The bifurcated supports 28 provide two positions inwhich the chuck assembly can be held against horizontal movement.

A is positioned shaft assembly F comprising the main shaft 35 journaledin the adjustable bearing assemblies 36 which provide verticaladjustments by means of'set screw 37 and horizontal adjustment by meansof screws and nuts 38.

' The diameter of shaft 35 is greater between bearings 36, the ends ofsaid enlarged part being threaded as at 39 and washers 40, positionedbetween the ends of said enlarged parts and the bearings 36 serve asthrust bearings. 35 extends beyond one of said bearings 36 and isrotated by any desired source of power. Approximately midway between thebearings 36 and The shaft directly above lever 34 there is mounted onshaft 35 a cylinder 41 having a continuous cam groove 41a in its outersurface. A pin 42 extendsv upwardly from one end of lever 34 and intothe cam groove of cylinder 41. When shaft 35 rotates the diagonal camgroove changes position causing lever 34 to oscillate. Sleeves 43 aremounted on said shaft 35 at each side of cylinder 41 and are secured soas to rotate with the shaft by means of nuts 44 screwed on the threadedportions 39 of the shaft. Also mounted on shaft 35 and adjacent the endsof reservoirs 30 are grooved soft rubber wheels 45 which are engaged bythe drive wheel 7 on the chuck and are yieldable vertically to allow atumbler on chuck to be moved into full contact with discs E. The paintapplying discs E are mounted on the sleeves 43 of the shaft 35, arespaced as desired by spacing members 46 and are secured in such positionby nuts 47 tightened on the threaded ends 48 of sleeves 43.

Paint applying discs E each comprises a steel ring 49, the outerperipheral surface of the ring having a width correspondingapproximately to the width of the band to be painted on the tumbler. Thering 49 is held frictionally between a pair of discs 50 screwed to a hub51, the hub and discs being clamped on sleeve 43 between a pair of thespacing sleeves 46. Positioned between the hub 5l and the ring 49 is acurved band spring 52. By this construction the paint applying discs Eare yieldable and accordingly align themselves to the surface of theperiphery of the tumbler to be banded and automatically compensate forany irregularities in the surface of the tumbler and for any unequalwear in the edges of the discs.

In operation; The reservoirs are llcd with paint or enamel of the colorsdesired. The paint applying discs are arranged on the main shaft innumber and position according to design to be placed on tumbler. Thechuck assembly is swung up out of contact with the discs and a tumbleris placed on chuck 10 which has been angularly adjusted by stud` and nut3a in accordance with the taper of the tumbler and the tumbler and chuckmoved in against spring l1 until the rim of the tumbler contactsgstopmember 8 and the inner edge of the rim contacts the centering disc 8a.'Then the locking mechanism is pivoted downwardly until bearing member 19is substantially opposite the center of the bottom of the glass, thescrew and nut means 22 being adjusted to stop the locking mechanism whenswung down to this position. Locking lever 17 is then allowed to swinghorizontally by spring 1'6, thus causing bearing member 19 to contactthe base of the tumbler. The chuck assembly is then pivoted downwardly,arm 4 fitting within bifurcated member 28, drive wheel 7 within one ofthe yieldable grooved wheels 45 which yieldably limits downward movementand also rotates chuck and the constantly rotating paint applying discscontacting the periphery of the tumbler. Due to the friction betweendrive wheel 7 and grooved wheel 45, chuck 10 and tumbler 9 are caused torotate. The discs moving through the paint reservoirs pick up paint andtransfer it to the side of the tumbler as they rotate against it. Assoon as the banding has been thus completed from one reser- :voir thechuck is swung upwardly by means of handle 5, taking the tumbler out ofcontact with the discs and the knurled wheel 6 is manually rotated tospin the tumbler and smooth out any gobs of paint left by-the discs.This first operation has produced the bands of any desired color asindicated by X in Fig. 9. The chuck assembly is then manually movedhorizontally'by means of carriage member B until the tumbler is abovethe second reservoir at which point it is swung down, arm 4 fittingwithin the next member 28 and drive wheel 'I on the next grooved wheel45, the second series of discs contacting the periphery of the tumblerbetween the bands heretofore made or according to their spacing. Thesecond reservoir being lled with different colored paint, differentcolored bands result when the discs are rotated against the tumbler.Thus a second series of bands is applied to the tumbler of a colordifferent than that of the rst series such as illustrated by Y, Fig. 9.

It is obvious that many different designs can be so produced, the numberof colors being determined by the number of paint reservoirs, the numberof bands by the number of discsand the design by the spacing andrelative position of the various series of discs. Should additionalcolors be desired without adding to the number of reservoirs it isentirely practical to supply partitions for the reservoirs (as indicatedat 53 in the right hand reservoir shown in Fig. 2), dividing them intosections, each section adapted to receive a differently colored paint.

The cushioned chuck 10 and stop member 8 enables the bands to be applieduniformly to all tumblers of the same size, for when the rims oftumblers applied to the chuck 10 contact stop 8 and are held in thatposition by the locking mechanism the relative position of the tumblerand the paint applying discs is always the same.
